# What is an Energetic Transmitter Word™?

This is in the spirit of the What is a Word/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.

If a word conforms to a special rule, I call it an Energetic Transmitter Word™.

Use the following examples below to find the rule.

• How does one make those aesthetically pleasing charts?! – greenturtle3141 Sep 9 '16 at 23:55
• @greenturtle3141 I've made mine in Excel, and took a screenshot. Not the most elegant, but it works out nicely. – Phlarx Sep 10 '16 at 3:22
• @greenturtle3141 Mine is from Excel, too. – Engineer Toast Sep 10 '16 at 11:14

I think an ETW is one that

contains the letters of a radioactive element (i.e., one with no stable isotope).

Specifics, which also explain why IMMUNOTHERAPEUTIC is extremely energetic:

BUCKMINSTERFULLERENE: BERKELIUM
COMMUNICABLE: NOBELIUM
COMPULSION: POLONIUM
DUMBFOUNDING: DUBNIUM
ENTHUSIASM: HASSIUM
HOMEBUILDER: BOHRIUM
IMMUNOFLUORESCENCE: FERMIUM
MICROFAUNA: FRANCIUM
MOUNTAINEERING: ROENTGENIUM
TANTALIZES: ASTATINE
UNIMAGINATIVENESS: EINSTEINIUM
IMMUNOTHERAPEUTIC: CURIUM
IMMUNOTHERAPEUTIC: TECHNETIUM
IMMUNOTHERAPEUTIC: ACTINIUM
(and there are, so Engineer Toast assures me and I have no trouble believing, several others that likewise go into IMMUNOTHERAPEUTIC besides those three)

I confess I haven't checked all the non-ETWs.

• Seems too well put together to be wrong. These are getting answered quicker than I can get a chance to look at them! – Avik Mohan Sep 10 '16 at 0:04
• Occupational hazard of being in a venue full of clever people. I'm sure everyone here has seen plenty of puzzles come and go before they have a chance to attempt them. – Gareth McCaughan Sep 10 '16 at 0:06
• This is correct and has excellent formatting! Can you find all 11 elements in the last word? (I think it was 11. The file is at work but I remember is was a startlingly large number.) – Engineer Toast Sep 10 '16 at 0:45
• I expect I can, but I really don't want to :-). – Gareth McCaughan Sep 10 '16 at 1:03
• But I'll add a remark in the answer to the effect that the three I've given are by no means all of them. – Gareth McCaughan Sep 10 '16 at 1:03
